Sata Data Transfer Rate. As an example it may read like this. Sata iii revision 3x interface formally known as sata 6gbs is a third generation sata interface running at 60gbs.

This sata version runs at 3gbs with a bandwidth throughput of 300mbs. Data transfer rate. However sata 1 dont support native command queuing ncq.
Data transfer rates.
While data is actually sent at 6 gbs it is encoded to counteract two common defects in telecommunications dc bias and clock recovery. As of 2010 a typical 7200 rpm desktop hdd has a disk to buffer data transfer rate up to 1030 mbits. The interface itself runs at 15gb while the bandwidth throughput is 150mbs. On our website the data transfer rate that is listed under specifications is always the theoretical value of any given interface.
